Or day to day even. 5000-6000 passengers come through my checkpoint on average but days when the numbers go over 8000 aren't all that uncommon. But even on busy days there are slow periods when most of the flights have already boarded and there is not many people going through. So yeah we all mull around for a little while until the next rush comes in and it picks up again. But of course people come through the checkpoint once in a day during the lull and here comes the thousands standing around comments.
Or even better is since we don't have a nearby break room a lot of us just eat our lunch at the seats behind the checkpoint and of course we always hear the comments about TSA employees not working. God forbid we should get to eat.
